/edit Given that it is due to happen on Tuesday 5 Dec 06, we'd like to recommend that authors not upload to the 2.0 Beta category any longer but instead just update their "live" versions at this point. Just put a temporary disclaimer at the top of your description stating that this version is for 2.0 and not to use it on live servers before Tuesday.
As you update your live versions, feel free to send a PM to one of the site staff with a link to the 2.0 Beta section version and we will delete it for you so as to avoid confusion.
Since it's likely going to happen within the next couple of weeks: just a quick reminder that when 2.0 goes live, we will be deleting the 2.0 Beta download category. At that point you will need to go back to the standard practice of updating the "live" version with your 2.0 updated version.
Current word from Blizzard is 5 Dec for the patch.
